Cellular localization of ERα and their apoptotic effects<br />

<br />

<br />

The actions of estrogen have traditionally been thought to occur through binding<br />

estrogen receptors in nucleus. Recent data, however, support the idea that some<br />

of ERα in the cytoplasm of various target cells are localized in mitochondria.<br />

Moreover, ERα collaborates with a number of factors on cell membrane, in<br />

cytoplasm, and nucleus to effectively modulate transcription of distinctive<br />

groups of target genes. While some of these factors appear to regulate the<br />

chromatin configuration by controlling histone modifications at the promoter,<br />

others are members of various kinase cascades. In order to discern functions and<br />

interactions of ERα and its coregulators, we allocated ERα to different locations<br />

in ERαnegative Ishikawa cell, using permanent transfection technique. In this<br />

report the antiapoptotic effects were examined for ERα at different cellular<br />

locations in the presence of inhibitors for EGFR, PI3K, MEK, and p38MAPK.<br />

Cellular alterations in proliferation, membrane potential, and caspase activities<br />

were examined using immunohistochemistry, flow cytometry, and related<br />

techniques. The present results might shed light on different pathways of ERα<br />

signal transduction.<br />
